The Hopewell tradition, also called the Hopewell culture and Hopewellian exchange, describes a network of precontact Native American cultures that flourished in settlements along rivers in the northeastern and midwestern Eastern Woodlands from 100 BCE to 500 CE, in the Middle Woodland period. The Hopewell tradition was not a single culture or society but a widely dispersed set of populations connected by a common network of trade routes.
The Cahokia Mounds State Historic Site is the site of a pre-Columbian Native American city directly across the Mississippi River from present-day St. Louis, Missouri. This historic park lies in south-western Illinois between East St. Louis and Collinsville. The park covers 2,200 acres (890 ha), or about 3.5 square miles (9 km2), and contains about 80 manmade mounds, but the ancient city was much larger. At its apex around 1100 CE, the city covered about 6 square miles (16 km2), included about 120 earthworks in a wide range of sizes, shapes, and functions, and had a population of between 15,000 and 20,000 people.
In archaeology, timber circles are rings of upright wooden posts, built mainly by ancient peoples in the British Isles and North America. They survive only as gapped rings of post-holes, with no evidence they formed walls, making them distinct from palisades. Like stone circles, it is believed their purpose was ritual, ceremonial, and/or astronomical.
Fort Ancient is a Native American earthworks complex located in Washington Township, Warren County, Ohio, along the eastern shore of the Little Miami River about seven miles (11 km) southeast of Lebanon on State Route 350. The site is the largest prehistoric hilltop enclosure in the United States with three and one-half miles (18,000 ft) of walls in a 100-acre (0.40 km2) complex. Built by the Hopewell culture, who lived in the area from the 200 BC to AD 400, the site is situated on a wooded bluff 270 feet (82 m) above the Little Miami. It is the namesake of a culture known as Fort Ancient who lived near the complex long after it was constructed.
The Mississippian culture was a Native American civilization that flourished in what is now the Midwestern, Eastern, and Southeastern United States from approximately 800 to 1600, varying regionally. It was known for building large, earthen platform mounds, and often other shaped mounds as well. It was composed of a series of urban settlements and satellite villages linked together by loose trading networks. The largest city was Cahokia, believed to be a major religious center located in what is present-day southern Illinois.
Many pre-Columbian cultures in North America were collectively termed "Mound Builders", but the term has no formal meaning. It does not refer to specific people or archaeological culture but refers to the characteristic mound earthworks that indigenous peoples erected for an extended period of more than 5,000 years. The "Mound Builder" cultures span the period of roughly 3500 BCE to the 16th century CE, including the Archaic period, Woodland period, and Mississippian period. Geographically, the cultures were present in the region of the Great Lakes, the Ohio River Valley, Florida, and the Mississippi River Valley and its tributary waters.
The Adena culture was a Pre-Columbian Native American culture that existed from 500 BCE to 100 CE, in a time known as the Early Woodland period. The Adena culture refers to what were probably a number of related Native American societies sharing a burial complex and ceremonial system. The Adena culture was centered on the location of the modern state of Ohio, but also extended into contiguous areas of northern Kentucky, eastern Indiana, West Virginia, and parts of extreme western Pennsylvania.
Hopewell Culture National Historical Park is a United States national historical park with earthworks and burial mounds from the Hopewell culture, indigenous peoples who flourished from about 200 BC to 500 AD. The park is composed of four separate sites open to the public in Ross County, Ohio, including the former Mound City Group National Monument. The park includes archaeological resources of the Hopewell culture. It is administered by the United States Department of the Interior's National Park Service. It was designated a part of Hopewell Ceremonial Earthworks World Heritage Site in 2023.
Warren King Moorehead was known in his time as the 'Dean of American archaeology'; born in Siena, Italy to missionary parents on March 10, 1866, he died on January 5, 1939, at the age of 72, and is buried in his hometown of Xenia, Ohio.
The Archaeological Conservancy is a 501(c)(3) non-profit organization that acquires and preserves archaeological sites in the United States. Whereas nearly every other nation protects all archaeological sites within its borders as part of its national patrimony, in the United States archaeological resources on private land are the private property of the landowner. As a result, archaeological sites in the United States are subject to destruction by urban development and sprawl, mechanized agricultural and land-leveling, and commercial looting to fuel the antiquities trade. By the 1970s the extent of archaeological site loss was increasing recognized as a crisis for the scientific study of the nation's past.
Moorehead Circle was a triple woodhenge constructed about two millennia ago at the Fort Ancient Earthworks in the U.S. state of Ohio.
The Newark Earthworks in Newark and Heath, Ohio, consist of three sections of preserved earthworks: the Great Circle Earthworks, the Octagon Earthworks, and the Wright Earthworks. This complex, built by the Hopewell culture between 100 BCE and 400 CE, contains the largest earthen enclosures in the world, and was about 3,000 acres in total extent. Less than 10 percent of the total site has been preserved since European-American settlement; this area contains a total of 206 acres (83 ha). Newark's Octagon and Great Circle Earthworks are managed by the Ohio History Connection. A designated National Historic Landmark, in 2006 the Newark Earthworks was also designated as the "official prehistoric monument of the State of Ohio."
Obsidian Cliff, also known as 48YE433, was an important source of lithic materials for prehistoric peoples in Yellowstone National Park near Mammoth Hot Springs, Wyoming, United States. The cliff was named by Philetus Norris, the second park superintendent in 1878. It was declared a National Historic Landmark in 1996.
The Portsmouth Earthworks are a large prehistoric mound complex constructed by the Native American Adena and Ohio Hopewell cultures of eastern North America. The site was one of the largest earthwork ceremonial centers constructed by the Hopewell and is located at the confluence of the Scioto and Ohio Rivers, in present-day Ohio.

Everett Knoll Complex, also known as Everett Mound is a Hopewell site in Northeast Ohio near the unincorporated community of Everett within Cuyahoga Valley National Park. It consists of a ~16 ft (4.9 m) diameter mound directly south of Everett road and habitation sites surrounding it.
The Mount Vernon Site, also known as the GE Mound, is a Hopewell site near Mount Vernon in southwest Indiana. The site was discovered and mostly destroyed in 1988 during road construction at a General Electric plastic manufacturing facility. The mound was partially leveled, used for road fill, and subject to widespread looting shortly after its discovery, resulting in a contentious and precedent-setting prosecution under the Archeological Resources Protection Act. It was one of the five largest recorded Hopewell mounds before its destruction. The depth and breadth of artifacts recovered from the site are some of the most significant of all Hopewell sites and even in its degraded condition it is one of the most significant Hopewell mounds yet discovered.
